Get a 7D now or wait?

I been wanting the 7D for a while ever since I sold my 50D and made due with a G11. But missing the DSLR since I gave up my 50D.

Should I get the 7D now or wait for its successor. Reasons, perhaps has SDHC card slot (I know CF cards are more pro but the SD are more convenient and I have plenty of them), Not sure if I want a articulating screen for the occasional self portrait when hiking or on holiday.
Any advice? the prices seem right cheap now for a 7D body $1330
